Doctors say that standing posture when working helps reduce the risk of cardiovascular disease, diabetes, digestion and increase life expectancy. Currently, some teachers of RMIT University in Ho Chi Minh City have adopted a standing posture when working. These teachers said sitting for too long to do lesson plans caused them back pain and varicose veins.

"After switching to a standing working position, I feel more comfortable. This change helps reduce the risk of diseases caused by sitting for too long, such as obesity, because the standing position consumes more energy." , Ms. Caro Nguyen shared. 

Health expert David Agus said that sitting at work for 5 hours or more continuously has the same health effects as smoking a quarter of a pack of cigarettes. Sitting for two more hours increases the risk of cardiovascular problems by 125%, including chest pain and heart attack, and shortens life by 46%.

The doctor explained, the human body is structured with movement. When the body has to sit motionless for many hours, the metabolism slows down, energy metabolism is poor, excess fat is formed, arthritis and many other diseases.

Standing helps control and lower blood sugar. This posture reduces cardiovascular diseases by increasing blood circulation, avoiding many life-threatening risks. Therefore, to work and stay healthy, office workers can change their working posture.

However, standing for hours at work also causes blood to pool in the legs and increases the risk of varicose veins. Therefore, you should combine standing and sitting to work. The worker can sit for 20 minutes after standing continuously for one to two hours to reduce pressure on the joints. In addition, you should do some muscle contractions to help blood circulation and avoid office diseases such as muscle pain, spinal pain.

If there is no condition to stand up after 20 minutes of sitting, solutions such as sitting on a swivel chair with a spring or on a big ball also make the muscles move and still focus on working. The right type of ball is the type commonly found in the gym, compatible with the height of the person and the table.

If you choose to work standing, you should choose a desk with a standard height, lower than your elbow so that your hands are perpendicular to the keyboard when standing upright. It is recommended to keep the screen 50-70 cm away from the eyes, tilt the monitor back 20 degrees and adjust the screen height so that the eyes are slightly down.

This way is a bit difficult for laptop users because the screen height cannot be adjusted. You should look for a two-tier desk or a multi-tier desk that can be adjusted to a height for standing people. Alternatively, you can use a book, paper box, or other object to raise the laptop to eye level.
